Title: Electro-mechanical periodically winding device for winding the spring of a clockwork mechanism
IPC: G04C1/06
Filed: 1936-06-04
Abstract: 469,698. Clockwork mechanisms. FOUQUES, R., and LENFANT, J. June 4, 1936, No. 15667. Convention date, July 3, 1935. [Class 139] Apparatus for winding the spring of a clockwork mechanism includes an electric motor 47 with a commutator 24 and means for slidably moving at least one of the brushes 22, 23 into and out of contact with the commutator. The spring is housed in a barrel 7 carrying a pin 6 which, as the spring unwinds, rotates a member 5 carrying two pins 9, 10. Pin 6 also rotates a wheel 8 in gear with the usual clock mechanism. Pin 6 and member 5 make one rotation an hour so that each half-hour the pin 9 (or 10) meets the end of a lever 11 and depresses it about a pivot 12 so that a pawl 13 on it is drawn back over a tooth of ratchet wheel 15. When pin 9 wipes free of lever 11, a spring 21 returns the lever 11 and pawl 13 upwards to drive through one tooth the ratchet 15, to which latter is attached a cam disc 16 having a notch for every two ratchet teeth. The top end of arm 17 rises into a notch of cam 16, allowing spring 46 to rock the rigid arms 17, 18 counterclockwise about the pivot 20. At its outer end, the arm 18 carries an insulating member 19 supporting two brushes 22, 23 for the commutator 24 of the winding motor 47. Brush 22 is always in contact with the commutator and by the counterclockwise rotation of arm 18 the brush 23 is now brought into contact to energize the motor. The latter winds the spring in barrel 7 and drives a train of which a wheel 38 carries two pins 40, 41. After a wind equal to the amount the spring has run down in half an hour, the pin 40 (or 41) acts on the lever 11 in the same way as the pin 9 (or 10) and rotates the ratchet 15 one tooth whereby the end of arm 17 is forced out of the cam notch to cause lowering of brush 23 and de-energization of the motor 47.

Abstract: 447,806. Drying wood. LACASSE, V., 9, ChaussÚe de Bonheyden, Pasbrug, near Malines, and COOLEN, E., 23, Rue de l'Empereur, Malines, Belgium. Oct. 23, 1934, No. 15735 /35. Divided out of and addition to 447,752 under which a Specification was laid open to inspection under Sect. 91 of the Acts, April 25, 1935. [Class 34 (ii)] The invention relates to improvements in apparatus for drying wood as described in the parent Specification in which the sap is extracted from. the wood as a liquid and not as a vapour. The drying chamber consists of an outer chamber 1 and a two part inner chamber 3 with heating coils as before. A vacuum pump 8 applies suction and intermediate baffles 12 are arranged between the layers of timber so as to facilitate air circulation and act as deflectors to catch sap and drain it away from the timber in the lower layers. A plurality of outlets 6a distribute the suction effect around the chamber 3. The heating coils are connected to a boiler 13, gas heated at 14 and provided with a supply tank 15 and pump P. Automatic control of the system whereby no vaporization of the sap is permitted consists of electric means operating a valve 17 in the gas supply and similar control of the vacuum pump 8. A magnet 18 is placed in the electric circuit including a thermostatic switch 19 in the chamber 3. A switch board 20 has a plurality of contacts 21, 22, 23, connected to corresponding switch positions 21a, 22a, 23a. The valve 17 is contained in a gas tight chamber 25 and is operated to close as soon as the temperature in the chamber 3 reaches the pre-arranged upper unit 23a on the thermometer. On the temperature falling, the gas is relit by a byepass 27. The degree of vacuum is arranged by a, fixed contact 30 and a movable one 31 held in tension by a spring 32. To the contact 31 there is connected a piston 33 in a cylinder 34 with an outlet 35 to the suction space between the inner and outer chambers 3, 1. During the pumping the pressure on the chamber side will be reduced till the pressure on the contact side of the piston is greater than that of the spring 32 and the chamber pressure. The contacts 30, 31 will then open to cut out the motor 29. The chamber 3 has a separate thermometer 36 and vacuum gauge 37 for checking purposes. The predetermined limits of temperature at which the gas valve operates are 30‹ C., 40‹ C., and 50‹ C., but other limits may be set. At the top of the chamber 1 is an inlet 38 with a two way valve 39 controlling a vent 40 to the atmosphere and a pipe 41 connected to a container 42. In the container may be a microbicide or a liquid for impregnating, fire proofing or waterproofing the timber subsequent to drying. Either the container may be connected to the chamber 1 or air may be admitted to break the vacuum. The timber might be impregnated with ammonia to produce the appearance of age.

Abstract: 1365509 Antistatic compositions MONSANTO Ltd 19 April 1972 [19 May 1971] 15809/71 Headings C3G and C3P A thermoplastic synthetic resin is compounded with up to 5% by weight of a trialkylthiourea as an antistatic agent. The alkylthiourea is stated to act by reducing the electric field at the surface of the resin which is produced by electric charges trapped in the interior, rather than by migrating to the surface and there allowing surface charge to dissipate, as conventional antistatic agents do. Exemplified resins are polystyrene grafted on to polybutadiene, and polyethylene, which are compounded with trin-butylthiourea. A conventional antistatic agent such as lauric diethanolamide or N,N- diethoxylaurylamine may also be incorporated.

Title: Improvements in or relating to lever gear mechanism particularly for operating vehicle brakes
Inventor: HILLS DERRICK ERNEST
IPC: B60T7/10
Filed: 1952-06-24
Abstract: 715,787. Linkwork. RANSOMES & RAPIER, Ltd. May 14, 1953 [June 24, 1952], No. 15853/52. Class 80 (3) [Also in Group XXXIV] A lever gear mechanism for transmitting movement to a part to be operated has a twospeed ratio action giving an initial movement providing rapid take up of slack followed by a movement at a greater leverage for applying a load. From the release position, as shown, the first part of the applying movement on the lever causes a profile 6, 7 on a cam 5 to press outwardly a follower roller 8 so that a link 10 is pivoted about a pin 11 and a torque is applied to the operating shaft 14 through a compression spring 17 on a guide rod 15. On further movement of the lever 1, the cam slope 7 becomes circular and causes no further displacement of the roller 8. At a later stage a pawl 23, which has been held out of engagement with a toothed quadrant 18 by a follower 25 bearing on the upper surface of a fixed ramp 26, engages the quadrant 18 and the lever 1 then applies the load through a link 20 pivoted to arm 13 at a lower speed ratio. If it should occur that slack in the mechanism has been taken up before the cam follower 8 has been fully displaced, any further displacement thereof will be absorbed by the compression spring 17. The lever is also provided with a conventional ratchet not shown, operated by lever 29 for locking at any position on toothed quadrant 27.

Abstract: 102,153. Gillot, H., and Roos, I. Nov. 9, 1915, [Convention date]. Grab-buckets.-The jaws 1 of the bucket are connected by pivoted rods 3 to the lower sliding block 5, which can be coupled to the upper sliding block 9 by the engagement of the bolts 7, 21, Fig. 2. The bolt 21 is cut away as shown, and is provided at one end with a collar 22 cut away to form a stop 23 for the end of a vertical locking- pin 24 mounted on a lever 25. One end of the lever 25 is pivoted in the block 9, and the other end is screwed into the spring-pressed sliding block 17 carrying the pulley 13, over which the rope 15 passes. To the other end of the bolt 21 is secured a weighted lever 29, Fig. 5, formed at one end with a broken flange 31, the ends of which are engaged by a pawl 35 carried by the block 5. A sliding block 40, having a projection 39 and carrying rollers 41, 42 at its ends, is mounted in the block 5 and is moved by the engagement of the rollers with guides 43, 44 during the movement of the blocks to bring the projection 39 into and out of the path of the weight 30. Assuming the jaws to be in the position shown in Fig. 1 and resting on the material to be lifted, an upward movement of the cable 16 raises the block 9, and the pawl 35 turns the lever 29 from the position shown in Fig. 5 into a position in which the pin 24 engages behind the stop 23 and the lever cannot fall back. The pawl is then disengaged from the flange 31, and continued lifting results in the closing and filling of the jaws. When the grab has been lowered to the discharging point and the weight has been taken off the cable 16, the ropes 14, 15 are slackened, and the pulley 13 is forced down by the spring 19, resulting in the release of the locking-pin 24 and the rotation of the bolt 21 under the action of the weighted lever 29. The bolts 7, 21 are then disengaged, so that upward movement of the cable 16 causes the discharge of the jaws. During the lowering of the open grab on to the material to be raised, the projection 39 raises the lever 29, and the parts again take up the position shown in Figs. 1 and 5.
